Reflex - 3/4 Inch Anti-Legionella Valve

The Anti-Legionella Valve is designed for use with a wide range of Reflex Refix anti-legionella vessels, helping to support safer and more hygienic hot water system operation. Installed in a vertical orientation, this valve encourages water to flow into and out of the vessel as hot water is drawn off, helping to reduce stagnation and maintain water quality within the system.

By promoting regular water movement, the valve helps minimise conditions that can contribute to bacterial growth, including Legionella. It also provides isolation functionality, allowing the expansion vessel to be removed more easily when maintenance or replacement is required. Its easy-fit design makes it a practical addition to compatible potable water installations.

Anti-legionella valves are commonly used in hot water systems where maintaining water hygiene is especially important, including healthcare facilities, hotels, public buildings and other high-demand installations. By helping control system conditions and reduce stagnant water, the valve supports safer operation and improved protection of potable water quality.
